If bcde is congruent to qpqr then cd is congruent to ?

answer:

step-by-step explanation: her feetare square

answer:

the x-coordinate is 6

step-by-step explanation:

a parabola is a two-dimensional, mirror-symmetrical curve, which is approximately u-shaped when oriented as shown in the diagram below, but which can be in any orientation in its plane. it fits any of several superficially different mathematical descriptions which can all be proved to define curves of exactly the same shape.

answer:

x = 3 ,   y = 1   (see attachment)

step-by-step explanation:

solve the following system:

{y = 4 - x

{y = x - 2

hint: | perform a substitution.

substitute y = 4 - x into the second equation:

{y = 4 - x

{4 - x = x - 2

hint: | choose an equation and a variable to solve for.

in the second equation, look to solve for x:

{y = 4 - x

{4 - x = x - 2

hint: | isolate x to the left hand side.

subtract x + 4 from both sides:

{y = 4 - x

{-2 x = -6

hint: | solve for x.

divide both sides by -2:

{y = 4 - x

{x = 3

hint: | perform a back substitution.

substitute x = 3 into the first equation:

{y = 1

{x = 3

answer: {x = 3 ,   y = 1

answer:

n=-4

step-by-step explanation:

6n + 9 = -3n - 21 - 6

add 3n to each side

6n+3n + 9 = -3n+3n - 21 - 6

9n+9 = -27

subtract 9 from each side

9n+9-9 = -27-9

9n = -36

divide each side by 9

9n/9 = -36/9

n = -4
